ALBERT N. FRIESVAND ALBERT H. HOVER, OF CINCINNATI, OHIO.

WINDOW-SHADE ADJUSTER.

Specification of Letters Patent.

Patented June `e, 1909.

Application led December 16, 1908. Serial No. 467,853.

To all whom it may concern:

Be it known that we, ALBERT N. FRIEs and ALBERT H. HOVER, citizens ofthe United States, residing at Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inWindow-Shade Adjusters, of which the following is a specification.

Our invention relates to improvements in window-shade adjusters.

One of its objects is to provide an improved adjuster for attachment tothe upper cross-bar of the shade, and which is adapted to be securelyattached to either wide and heavy cross-bars, or to narrow or lightcrossiars. f

Another object is to provide an improved manner of attaching and holdingthe adjuster to the cross-bar, and another object is to provide asimple, strong and durable adjuster attached to the cross-bar andcarrying an eye and a suspending cord to hold the shade in any desiredposition.

It further consists in certain details of form, combination andarrangement, all of which will be more fully set forth in thedescription of the accompanying drawings in which:

. Figure l. is a front elevation of a window frame and shade with ourimproved adjuster attached. Fig. 2. is an enlarged detail sectional view'of the adjuster on line 0a a: ot Fig. 1. Fig. 3. is an enlarged topplan view of the adjuster attached to a wide cross-bar. Fig. A. is aview similar to Fig. 3. showing the adjuster attached to a narrowcross-bar. Fig. 5. is a perspective view of the adjuster detached andviewed from the rear. Fig. 6. is a detail sectional view of amodification.

In the accompanying Vdrawings A rep.

resents the window-shade which is supported and adapted to be wound upona shade roller B which is supported in hangers Z) b carried by an uppercross-bar C which is suspended by a cord F from a catch pulley D at thetop of the window Jframe E. The cross-bar C is adapted to be raised orlowered and supported at any desired elevation by means of the cord F,and its engagement with the catch pulley D.V

In practice the cross-bars C vary in all their dimensions, this is dueto variations in the width and length of the shades required, which inturn vary the weight of the shades and shade rollers. It is desirablethat the cross-bars vary in strength according to the .weight of theshade and roller used, and

also in order that the cross-bar and shade and roller may to a certainextent counterbalance each other, so as to hang in the desired position.Thus the adjuster to be interchangeable innature, is required to becapable of iirm attachment `to wide or narrow cross-bars, and capable ofadjustment so that the point of suspension or eye may be adjusted to aclose approximation over the center of gravity of the parts to besuspended as a whole.

Our improved adjuster is adapted to be attached to and support thecross-bar C and to provide an eye by which the adjuster is suspendedfrom the cord F. -It is desirable that the adjuster be capable ofinterchangeable attachment to cross-bars ot various dimensions, that itbe adjustable at the time of attachment to the cross-bar, so that theeye will be the requisite distance from the cross-bar, and that theattachment be of such nature as to retain the cross-bar in the desiredposition.

Our improved adjuster comprises two arms K K preferably of stii orspring sheet meta-l pivotally attached together at one end.

This may be elfected as shown in Figs. 2 to 5 l by means of the shank 1of the eye L which passes through the washer M, and the ends of the twoarms K K. and is threaded and secured in position by means of a nut m.It

may also be effected by means of a hollow 3 rivet M passed through holesin the ends ol arms K K and clenched as shown in Fig. G,

.the central opening m in the rivet serving as an eye for the attachmentof the cord F.

The free ends of arms K K are provided with a series of holes 7c soarranged that two screws may be employed to attach said arms to either awide or narrow cross-bar.

N represents braces or `fingers preferably of spring sheet metal whichare pivotally attached by rivets n to the rear 'tace of arms K K throughany of the holes c, according to the size of the cross-bar. In attachingthe arms K K to the cross-bar the fingers N bear against the frontof thecross bar with 5 su'liicient pressure to form a brace to hold theadjuster and cross-bar in the desired relative positions. The fingers Nare left long enough to support the front of the wide or deepcross-bars, and their ends may be i i trimmed 0E when fitting theadjuster to narrow cross-bars. Also if desired the free end a of fingersN may be perforated and secured to the cross-bar by tacks or screws. Asindicated in Fig. 2 the lingers N occupy a position between the shaderoller and the cross-bar so as not to interfere with the movements ofthe roller and shade. The lingers N being pivotally attached to arms K Kcan be adjusted to the desii'ed position,

and where constructed of spring metal will hate a ii'in but slightlyyielding pressure against the cross-bai'. Figs. 3 and t show the mannerot' adjustment of arms K K and plates N for both wide and narrowcrossbars.

Y e are thus enabled to provide a simple7 strong and durable fixture,capable of inter changeable attachment to various cross-bars, andtending' to retain the cross-bars in the desired position.

The device herein shown and desci'ibed is capable of considerablemodification without departing from the principle of our invention.

Havingl described our invention, what we claim is:

l. An article of the character indicated comprising arms pivotallyconnected to each other at one end and pi'ovided at the point oit.'their connection with an eye for the attachinent of a cord, the freeends of said arms being singularly adjustable and pierced with a seriesof holes for attaching' said arms to a cross-bar.

An article of the character indicated comprisii'ig a pair of arms, aneye for attaching a cord, said arms being' nected together at one end bythe shank of said eye, the free ends of said arms being' pierced with aseries of holes for attaching' said arms to a cross-bar and adapted tobe adjusted to varying angles to interchangeably tit dilierentcross-bars. I

pivotally con i t t l t t i t t t In combination with the cross bar otEa window shade, an adjuster comprising a pair of arms pivotiallyattached at one end to each other and provided with an eye tor theattachment oi a cord. the opposite ends of the respective ai'iiis beineVattached to the cross-bai'.

`it. An article olf the cliai'actei' indicated comprising' a pair olai'ins. pivotatty attached to each other at one end. and provided withan eye 'tor the attachment o'tl a cord. the tree ends of said arms beingadjustable to var \g*inl' angles and adapted to be attached to across-bai'. and braces pivotalty attached at intermediate positions onsaid arms.

5. In combination with a shade roller and cross bar suj'iportinn thesame. an adjuster comprisingY two arms pivotallv attached to each othei'atl one end and adapted to be attached to the cross bai' at theoppositey ends. downwardly projecting braces cai'i'ied by said arms andbearingy against the cross bar, and means for suspendingV said adjuster.

(5. .ln combination with a shade roller and cross-bai' supporting' thesaine. an adjuster comprising' two arms` pivotally connected to eachother with their opposite ends adjust able to varying :in les andadapted to be attached to the upper edge ot said ci'oss-bai'. down'ardly projecting' braces carried bv j said arms, adapted to'be attachedto the front ot' said cross bar. and means Yt'or suspending' saidadjuster.
